DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS

Hereinafter, an exemplary embodiment of the present invention will bedescribed with reference to the accompanying drawings.

As illustrated in FIG. 1, a mobile communication system includes mobilecommunication terminals 10 and a base station 20. The mobilecommunication terminal 10 includes a control part 11, a transceiver part12, an instructions input part 13, a voice input/output part 14, adisplay part 15 and global positioning system (GPS) receiver 16. Thecontrol part 11 controls general operation of the mobile communicationterminal 10. The transceiver part 12 communicates with the base station20. The instructions input part 13 is used for inputting informationrelated to operation of the mobile communication terminal. The voiceinput/output part 14 processes voice signals inputted or outputted. Thedisplay part 15 displays information related to operations of the mobilecommunication terminal under controls of the control part 11. And theGPS receiver 16 recognizes location of the mobile communication terminalbased on information received from satellites and provides the locationinformation to the control part 11. The instructions input part 13includes an operation button to instruct capture of information of othermobile communication terminals. Hereinafter, a mobile communicationterminal that instructs capture of information will be termed as a firstmobile communication terminal. On the other hand, mobile communicationterminals of which information are captured by the first mobilecommunication terminal's instructions will be referred to as secondmobile communication terminals. Herein, the second mobile communicationterminal is not required to comprise the instructions input part 13. Ifthe operation button is pressed by user, the control part 11 makes thetransceiver part 12 transmit to the base station 20 the locationinformation of the first mobile communication terminal obtained bydriving the GPS receiver 16, and capture signal to instruct capture ofinformation of the second mobile communication terminals. When thecontrol part 11 makes the transceiver part 12 transmit the locationinformation of the first mobile communication terminal to the basestation 20, it transmits an identification number of the first mobilecommunication terminal and current time information to the base station20 together.

The base station 20 ordinarily provides mobile communication service tothe mobile communication terminals 10 including the first mobilecommunication terminal and the second mobile communication terminalsand, in case of need, activates a process of capturing information ofthe second mobile communication terminals located within a certaindistance from the first mobile communication terminal based on locationof the first mobile communication terminal, according to instructionsreceived from the first mobile communication terminal. The base station20 includes a central processing part 21, a data storing part 22, and atransceiver part 23. The central processing part 21 controls generaloperations of the base station 20 and proceeds with processes forcapturing information of the second mobile communication terminals. Thetransceiver part 23 communicates with the mobile communication terminals10 including the first mobile communication terminal and the secondmobile communication terminals. The data storing part 22 storesinformation of the second mobile communication terminals captured undercontrols of the central processing unit 21.

With the above-described mobile communication system, in case that theoperation button to instruct capture of information of the second mobilecommunication terminals is pressed by user of the first mobilecommunication terminal in emergency situation, the first mobilecommunication terminal obtains location information of the first mobilecommunication terminal itself by driving the GPS receiver 16, andtransmits capture signal and the location information of the firstmobile communication terminal to the base station 20 through thetransceiver part 12 of the first mobile communication terminal. If thebase station 20 receives the capture signal and the location informationfrom the first mobile communication terminal through transceiver part ofthe base station, the base station 20 activates process for capturinginformation of the second mobile communication terminals, recognizeslocation of the first mobile communication terminal and designates setrange (for example, 10 m or 20 m from the first mobile communicationterminal) based on the location of the first mobile communicationterminal. Then, the base station 20 checks information of the secondmobile communication terminals located within an area of the basestation 20 and receives location information of the second mobilecommunication terminals through transceiver part of the base station 20by transmitting GPS driving signal to the second mobile communicationterminals through the transceiver part of the base station 20.Thereafter, the base station 20 gathers information of the second mobilecommunication terminals (e.g., identification number, locationinformation and current time information) and stores the information inthe data storing part 22. As described above, by providing a policestation with information of the second mobile communication terminals,stored in the data storing part 22 of the base station 20, it may bepossible to identify criminals who harm a user of the first mobilecommunication terminal.

The method for capturing information of other mobile communicationterminals according to an exemplary embodiment of the present inventionwill be described with reference to the FIG. 2.

At first, a user of the first mobile communication terminal presses theoperation button to instruct capture of information of the second mobilecommunication terminals, such as in emergency situation (S21). Then, thecontrol part 11 of the first mobile communication terminal obtainslocation information of the first mobile communication terminal itselfand makes the transceiver part transmit to the base station 20 thelocation information of the first mobile communication terminal andcapture signal to instruct capture of information of the second mobilecommunication terminals (S22).

Then, the transceiver part 23 of the base station 20 receives thelocation information and the capture signal from the first mobilecommunication terminal and forwards the location information and thecapture signal to the central processing part 21. The central processingpart 21 recognizes that capture of information of the second mobilecommunication terminals is instructed and activates a process to captureinformation of the second mobile communication terminals. Also, thecentral processing part 21 recognizes location of the first mobilecommunication terminal and sets a range for capturing information of thesecond mobile communication terminals (e.g. 10 m or 20 m from the firstmobile communication terminal) based on the location of the first mobilecommunication terminal (S23).

Also, the central processing part 21 of the base station 20 recognizesthe second mobile communication terminals located within an area of thebase station (S24) and transmits GPS driving signal to the second mobilecommunication terminals through transceiver part 23 (S25). The GPSdriving signal is a signal that instructs the second mobilecommunication terminals to drive the GPS receivers of the second mobilecommunication terminals. Then, the second mobile communication terminalsdrive their own GPS receivers to obtain their own location information,and transmit to the base station 20 the location information,identification number of the second mobile communication terminals andcurrent time information (S26). The base station 20 receives thelocation information, identification number of the second mobilecommunication terminals and current time information together (S27).

The central processing part 21 of the base station 20 receives thelocation information, identification number of the second mobilecommunication terminals and current time information through thetransceiver part 23 and recognizes the location information,identification number of the second mobile communication terminals andcurrent time information. The central processing part 21 stores thelocation information, identification number of the second mobilecommunication terminals and current time information in the data storingpart 22 (S28). By providing other information user such as policestation with the information stored in the data storing part 22 (S29),it may be possible to identify criminals who harmed a user of the firstmobile communication terminal. For example, as illustrated in FIG. 3,the range (Z) for capturing information of the second mobilecommunication terminals is set to have a certain radius “r” based onlocation of the first mobile communication terminal (MT1) thatinstructed capture of information of the second mobile communicationterminal. If one user of the second mobile communication terminals(MT2˜MT4) is a criminal who harmed the user of the first mobilecommunication terminal (MT1), it may be possible to obtain informationof the criminal based on information of the second mobile communicationterminals (MT2˜MT4).

As described above, according to the embodiments of the presentinvention, by capturing information of the second mobile communicationterminals located within a set distance from the first mobilecommunication terminal, according to instructions by user of the firstmobile communication terminal, it is possible to easily identify usersof the second mobile communication terminals.
